ZenSim eSIM Data Plans for Réunion

ZenSim does not have a true unlimited data eSIM for Réunion. All of their plans have a fixed data cap, such as 3 GB per day for the "Unl…” when it claims to be unlimited, or 10 GB, 20 GB, and 40 GB for fixed‑data options. Choosing a fixed data plan, for example the 40 GB 30‑day plan, can be more cost‑effective for most travelers who do not need continuous high‑speed data without limits.

ZenSim does not offer any eSIM plans for Réunion that include a phone number or SMS functionality. Travelers can only purchase data‑only eSIMs from ZenSim for that destination. Over the data connection, VoIP applications such as WhatsApp, Telegram, and iMessage can generally be used to make calls and send messages, but some destinations may block or restrict access to specific VoIP services. Travelers should check whether these apps are available in Réunion before buying a ZenSim eSIM plan.

ZenSim offers 13 single‑country data plans for Réunion and does not provide any multi‑country plans. The plans available vary from 1 GB up to 40 GB of data and are priced between roughly $5 and $77. Ten of the plans have a fixed data amount that lasts for the entire validity period, while three are daily data cap plans where the data allowance resets each day.
